Erosion Control in the Catalinas
February 24, 2026Join us in the Santa Catalina Mountains for a weekend building erosion-control structures in areas burned by the 2020 Bighorn Fire. Together, we can protect springs from landslides and ensure the mountain absorbs even more rain and snowmelt, recharging the aquifer that plants, wildlife, and people like us depend on. Note: Carpooling from Tucson is available, and day-trippers are most welcome. We’ll be camping at Whitetail Campground on Mt. Lemmon.

Project Mountain Recharge: Moving Rocks to Save the Rain on Mt. Lemmon
July 1, 2025In response to the 2020 Bighorn Fire, Sky Island Alliance has been working with the Arizona Conservation Corps and Coronado National Forest to build more than 250 erosion-control structures out of loose rocks. This helps protect springs, conserve soils, limit fire risk, and infiltrate rainwater and snowmelt in areas that were burned. Now, we’re planning to continue this restoration work around more springs, the community of Summerhaven, and other inhabited areas in the Catalina Mountains. Join SIA Stewardship Manager Bryon Lichtenhan for our next virtual Coffee Break to learn more about this project and how to get involved.
